Aubrianne Moore, 28, of Cedar Springs, Kent County, US, used a fake doctor’s note to get her children out of school then drove to a wooded area where she persuaded her daughters to leave the car one-by-one then gunned them down on February 18.
The mum then bundled the lifeless bodies of Kyrie, eight, Cassidy, six, and Alaina, two, back into her car and drove to her boyfriend’s house where she shot herself.
Her boyfriend, dad to two-year-old Alaina, discovered the horrifying scene an hour and a half later.
Tragically, Moore’s former social worker filed a petition to the Newaygo County Probate Court suggesting she be admitted to a mental hospital last September.
“She had some postings on Facebook and things like that that lead to believe she was paranoid and thought that the kids were in jeopardy somehow”

She reported: “Aubrianne is keeping her kids home from school because the television told her there would be a school bus accident today.”
She also wrote: “Aubrianne stays awake at night believing people will break into her home.
“Aubrianne is not eating believing food is being poisoned.”
Chillingly, she also noted: “I believe the individual has mental illness and as a result of that mental illness the individual can reasonably be expected within the near future to intentionally or unintentionally seriously physically injure self or others.”
Kent County Sheriff Michelle LaJoye-Young told US media it was apparent the mum had been seriously ill before the murder-suicide.
“Mom appears to have been struggling with pretty substantial mental health issues,” LaJoye-Young said.
“She had some postings on Facebook and things like that that lead to believe she was paranoid and thought that the kids were in jeopardy somehow.
“We suspect that led to the events this day.”
Moore was diagnosed with schizophrenia and psychosis in September last year and was involuntarily hospitalised for 10 days, according to NewayGo County Probate Court records.
